In the form of the invention shown in Figures 1 .to 8, the electrically operated door closing and locking mechanism is illustrated as associated with doors of the horizontally swinging type, the reference numeral 1 designating thebank building in-which the door opening 2 is :closed by the hinged doors 3.

The object of this invention is to provide devices for closing the doorsif the latter are in open position and also for holding thedoors against opening movement to prevent the escape of a person in the bank building 1, the-door operating mechanism being disposedbeneath the floor and eontrolled in its operation by one or more conveniently posi tioned: push button switches, the electric devicesalso flashing a signal to'the bank employee that the doors areproperly operating and moving to locked position while asignal is also givenat av distant point, such as at a The lower corner hinge or pivotal support for each of the swinging doors 3 forms a part of the dooroperating mechanism and as shown in Figures 1, and 6, there is provided a two-part bracket support in which the upper'part 4 in the form of an angle iron provided with angle strap extensions 5 that are embedded in the foundation wall 6 extending between the base floor 7 and the bank floor 8 The lower part 9 of the two part bracket is of, angle iron construction and is secured to the Wall6 by anchoring bolts 10 passing through the wall and retained by the 7 base plate 11. Spaced disk plates 12'and' 13 are carried by the parts 4 and 9 of the bracket and have interengaging portions 14; to prevent relative movement and also to hold the disk plates in spaced relation. The pivot bearing 15 for'the lower corner edge of each door 3 comprises a bolt'l6 with a U-socketlT at its upper end for supporting the lower edge to the door, the bolt 16 being rotatable through the bank floor, 8, while the under side of the bearing 1'1 is provided with a circular race of bearing balls 18 in a corresponding race in the disk plate 19 for the absorption of the end thrust ofthe bolt The lower end of the b olt16 extends through thedisk plates 12 and 13 andis retained in position by the cap nut 20. Each bolt 16 has an arm '21 fixed thereto between the disk plates 12 and 13 with bearing balls 22 interposedpbetween the arm 21 and disk plate;

The operating means for the arms 21 comprise electrically operated devices that are mounted upon'the tiers 23 between the walls 6, said devices comprising a box-like struc- 'ture or casing 2% supported upon the tiers 23,

-partment 25 and is interlockingly engaged open at itsupper. side-and divided into two compartments 25 by the central partition 26. Ablock 27 is slidably mounted in each com- .with the walls .of the compartment by the tongue and groove connections '28." A lever 29 is associated with each sliding block 27, the lever being pivotedas at 30upon the upper side of the casing 2% with a, pin and slot connection 31'between one end thereof and a sliding block while the other end of each lever 29 site directions to the doors 1 has a pin and slot connection 32 with an'adjacentarm 21. The slot 32'hasan ofi'set portion 33 at each end to receive the associated pin when the lever 29 moves to its limit in" oppoprcvent end vibrations of A longitudinal shaft 34'is journaled at its ends and also intermediate its ends in the easing 2a with the portions thereofextend- 'ing through the compartment 25 being re extends. WVhen the blocks 36 are positioned at the outer ends of the compartments25 as shown in Figure 2 the doors 3 are free to operate, each block 27 having an opening 38 therein for the free passage of the threaded portions of the shaft 34.

The shaft 34 is electrically operated for moving the blocks 36 toward the central cross partition 26 to hold the sliding blocks 27 against movement and when the blocks 36 are so disposed, the doors3 are retained in their closed position. An appropriate wiring arrangement .and operating means for the shaft 34 is shown in Figure 8, one end of the shaft 34 projecting from the casing 24- and having a beveled gear 39 fixed thereto that meshes with bevel gear 40 upon the shaft ell that-extends from the speed reduc ing gearing %2. The shaft l3 of the motor 44' communicates with the speed reducing gearing l-2- and when the motor circuit'is closed, the shaft 3% is operated for shifting the blocks36, the motortet being of the reversing type for causing a reverse rotation of the shaft 34: and sliding mevementof the blocks 36 in oppositedirections in the compartment-25 of the. casing- 24. The wiring arrangement includes line wiresa and b, the line wire at extending to the switch (Z which may be of the push button type that is located inthe bank building, the wire 6 front the push button switch cl extending 'to the switchfat a distant point, such as a police headquarters. The wire 9 that is associated with the push "button (Z extends to the transformer section it and continues therefrom at 2' to the contact 'j on the casing 2% that is supported by the insulating block k. The wire m from the transformer h extends to the bell 11 that is located in the police heads quarters. A second contact!) carried by the insulatingblock l: is connec-tedby the 'wire 9 to the lamp 9 located in the bank. the wire 1 continuing from the lamp to the terminal 45 of the motor 44: and "con-tinnii ig from the motor as at s to the line wire 7). Spare-d contacts I and 0 are conneieted by the bridge piece It on the sliding block 36 and completes the circuit. It will'therefore be understood that the bell at police headquarters rings while the lamp 9 in the bankis illuminated, and the motor 14; is being operated in the desired direction" for shifting theibloeks SG-tmvard each other and holding the blocks 27 that are connected ,to the doors ,S- against movement. During this movement, the bridge piece I; is displaced from the contacts 7' and oto break the circuit, themomentum of the motor shaft d3 insuring full movement of the blocks r The push button f in police headquarters conneCts the Wire 6 to the wireu that extends to the contact o upon the insulationblock w, the contact .70 upon the insulation block w being connected to the contact o bythe bridge piece t upon the othersliding blockBG that has beenmoved intoc-ontac't therewith, The wire 3 from the Contact leads to the terminal 46' ofthe motor i while the wire v extends from" the terminal to the return wire 8 that communicates with the line wire I). It will therefore be understood that when the push button f in the police headquarters is operated the motor 44 is driven in a re vcrsedn'ection to retract the sliding blocks 2-36 tothe outer ends of the compartment l hen the doors dare to be normally re tained'in' the closed position, but unlocked,

the spring deviceis associated with thelevers 29 for normally retaining the sliding blocks 27 inengagement with the intermediate partin-0112b, the spring 47 being anchored at its ends to the pins 31 as clearlyshown in Figure 2( I There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

It is obvious that minor changes may bemade ln' thef iorm and construct on of the in-:

vention with-out departing fromthe material spirit thereof. It is not, therefore, desired to confine the'invention' to the exactform herein shown and described, but it is desired to include all such as properly come within the scope claimed. I
